Update 21We are making great progress on Update 21, but we unfortunately can’t provide a release date yet. Update 20.5 is just a step on the way to make sure everything is running smoothly. Thank you for remaining patient!

We are now in February, and I still don't see any updates. The updates that I am expecting are bug fixes. There are so many bugs and glitches with Update 20.4. Those bugs involve the following.

1. Planets turn black when colliding with each other.

2. Large terrestrial planets disappear when colliding with small gas planets (gas giants) or (gas dwarfs).

3. Earth's textures are poor.

4. Earth ocean levels are too high in some places and too low in others. Please update Earth sea levels and texture. Examples are Florida is flooded, and Australia and New Guinea are joined together by low sea level.

5. When changing the luminosity of stars and their mass and radius, the star either resets back to default of disappears completely. Some stars don't like it when changing only the mass or the radius. That means when locking either the mass or radius, one or the other changes as well. Please add an option to lock both mass and radius for planets, gas giants and stars.

I am looking forward to Update 21. First of all, what I expect Update 21 to include is a mega list of bug fixes, because currently, Universe Sandbox 2 has far too many bugs and glitches. The 12 bugs that I reported in the post above is just to name a few, more occurring bugs, but there are many more bugs as well.

I am not happy at all that Universe Sandbox 2 has so many bugs now. Most of the time, I go back to use Alpha 16 because it has almost no bugs in simulations. For me Alpha 16 seems to be more perfect than Update 20.4.

I am very happy for the exciting features that developers have put in to continuously develop Universe Sandbox 2. I hope that Update 21 will make it possible to customize the colors of gas giants, stars, atmospheres and water. I am looking forward to a much better version of Universe Sandbox 2 when Update 21 comes out.

8. Earth's rotational period is 23.9 hours. That's wrong. It should be 24 hours long - 1 day.

23.9 hours is the siderial day of Earth, 24 hours is the solar day of Earth. Earth completes a single rotation every 23.9 hours, but the earth has to rotate a few degrees more so that, at noon, the sun would appear in the same position as yesterday

It is clear that Universe Sandbox 2 must now have an engine upgrade to make simulations run faster, smoother, and with more accuracy and performance. Also a huge demand by me and other people on this forum is that Universe Sandbox 2 must also have much better graphics. The graphics look like graphics from the 1990s computer games. I really find it so strange that now in 2018 we still have graphics similar to the 1990s era.

I am aware how tough and difficult it is for those brave developers working behind the scenes to create and further develop Universe Sandbox 2, but I would really appreciate if Universe Sandbox 2 had much, much better and shaper graphics, plus eliminating all of the annoying bugs and glitches that this universe simulator currently have. The quality of graphics is the number one important aspect to a good universe simulator so, I hope that much better and sharper graphics will be implemented in Update 21 hopefully.

I am so excited for the upcoming release of Update 21. For those of you who are aware of the news features, please can you explain to me in detail what kind of features are expected to come in Update 21.
